Recent Development of Two-Dimensional Gas Chromatography Mass Spectrometry and its Application

Xiao He*, Xuan Zheng*

The past decades have seen the fast development of multi- dimensional separation technologies, which are capable of separating increasingly complex mixtures. One good example is the comprehensive two-dimensional Gas Chromatography (GC × GC) that can achieve orthogonal separation by connecting two capillary columns with different stationary phases in series and obtain the total peak capacity. In this the new development of GC × GC and its application are discussed, including the upgrading of GC × GC and the modulators, the molecular identification of un-resolved complex compounds, and the significant environmental consequences, etc. The remarkable high peak capacity and the versatile features of GC × GC have attracted wide attention in environmental chemistry and the related disciplines and sub disciplines.
